CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 237,588, dated February8, 1881.

Application filed November 19, 1880.

To all whom it 'may concern:

Be it known that I, WILLIAM V. PERRY, of Chicago, in the count-y ofCook, and in the State of Illinois, have invented certain new and usefulImprovements in Car-Couplings; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification.

This invention relates to certain improvements in car-couplings; and ithas for its objects to provide for holding the coupling-pin in thedraw-head in such manner as to be at all times under the control of theoperator, whether to couple or uncouple, and to prevent any possibilityof losing the coupling-pin. The coupling-pin which I employ is the sameas the ordinary coupling-pin of elliptical crosssection, with theexception of the shoulders at the lower end. The draw-head is the sameas those usually employed on railroads, with the exception of twochambers situated one on each side of the coupling-pin aperture, nearits upper end. The above-mentioned objects I attain by theV mechanismand apparatus illustrated in the accompanying drawings, in which- Figurel, represents a longitudinal vertical sectional view of my improvedcar-coupling draw-head, showing the coupling-pin in erect position,resting upon any of the usual pinsupports, ready to be dropped home byan incoming link. Fig. 2 represents the coupling pin after being raisedto its highest limit and turned one-quarter of a turn either to theright or left, and allowed by its own gravity to stand inclinin g eitherforward or backward, and resting upon the inclined shoulders near itslower end. Fig. 3 represents a transverse vertical sectional view ofdraw-head, showing the upper end of the coupling-pin aperture and therecesses therein. Fig. 4 represents a top view of my draw-head with aportion of the lower end of the couplingpin in position, so as to bekept from falling home by the two inclined shoulders holding in therecesses at the opposite sides of the coupling-pin apertures. Fig. 5represents a transverse horizontal sectional view of the lower part ofthe coupling-head,

(Model.)

and Fig. 6 represents a view of thecouplingpin detached.

The letter A indicates the draw-heads, which may be of the ordinary orany approved construction.

The letter B indicates the coupling pin, which is elliptical incross-section.

The letter C indicates the coupling-pin aperture, which is alsoelliptical in cross section to correspond with the shape ofthe pin.

Near the lower end of the coupling-pin are formed the inclined shouldersD, upon which the pin is adapted to rest when fully elevated and givenone-quarter of a turn in either direction.

The letter E indicates two shoulders at the lower extremity of thecoupling-pin, which are adapted to engage the recesses F formed onopposite sides of the coupling-pin aperture when the pin is in itselevated position, the said shoulders preventing the pin from pullingout or being accidentally lost when thus elevated.

The letter G indicates the rivet usually employed at the lower end ofthecoupling-pin to confine it in its aperture, when directly elevated,before turning to set the shoulders E in the recesses. The ends ofthesaid rivet slide in the grooves H in opposite sides of thecouplingpin aperture provided for the purpose. y

The operation of my invention will be readily understood in connectionwith the above description, and is as follows When the coupling-pin isdown it holds the link in the ordinary manner. When elevated it freesthe link, and by turning said pin one-quarter of a revolution in eitherdirection it brings the inclined shoulders to bear upon the upper faceof the draw-head and throws the shoulders at its extremities into therecesses ais-opposite sides of the coupling-pin aperture, so as to keepthe pin elevated and hold it to its seat, as hereinbefore stated.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-
